Iranian President Mahmoud Ahmadinejad arrived in New York City on Sunday to attend the United Nations General Assembly this week.
His visit was met by demonstrators protesting his regime.
Ahmadinejad's visit came on the same day that freed American hiker Sarah Shourd returned to the U.S. Shourd, along with her two friends were arrested and accused of spying back in July of 2009.
Iran claimed Shourd, her fiance Shane Bauer and their friend Josh Fattal illegally crossed the border into Iran from Iraq.
During a news conference Sunday, Shourd said the three had been hiking in a popular tourist area - near a waterfall in Iraq's Kurdistan region - and had no idea the border was nearby.
"If we were indeed near the Iraq-Iran border, that border was entirely unmarked and indistinguishable," she said.
Shourd was released on $500,000 bail, because of medical concerns. She expressed her happiness for her own freedom, but sadness for her friends left behind.
"My disappointment in not sharing this with Shane and Josh was crushing," she said.
"Shane and Josh do not deserve to be in prison one day longer than I was," she said. "We committed no crime and we are not spies. We in no way intended any harm to the Iranian government or its people and believe a huge misunderstanding led to our detention and prolonged imprisonment."
The families of the two remaining hikers have asked to meet with Ahmadinejad.
"We're very glad that that lady was released," the Iranian president said about Shourd during an interview with the Associated Press.
"(Due) to the humanitarian perspective of the Islamic Republic chose to adopt on the subject, she was released on bail," Ahmadinejad said. "And we hope that the other two will soon be able to prove and provide evidence to the court that they had no ill intention in crossing the border, so that their release can also be secured."
